Warning! A hidden dragon has emerged!

Song Hongyan took the sandalwood box from Tan Min and handed it to Qin Quan.

A slight buzz from the alcohol made her eyes even more alluring and dreamy. She said solemnly:

"Mr. Qin, I know you are investigating the arson case that occurred in the suburbs of Jincheng ten years ago."

"Back then, my elder brother worked for the Hidden Dragon in Jincheng and personally participated in the rescue efforts during that fire. He also secretly investigated the clues afterwards. This wooden box contains all the investigation records from that time, and perhaps it contains the key evidence you're looking for."

Do you know what will happen if you lie to me?

Qin Quan suddenly looked up, his sharp gaze fixed on Song Hongyan in disbelief.

What he had been dreaming of and searching for was actually in the Song family.

Chen Shuang, Tan Min, and Liu Fei exchanged a smile, remaining silent as they watched the two men.

Song Hongyan has curved eyebrows and a graceful figure.

"Sir, you'll know once you open it."

Qin Quan had never been interested in ordinary things.

But the contents of the wooden box were related to the Qin family massacre case ten years ago. Without any hesitation, he immediately raised his hand and opened the sandalwood box.

Inside the box, a stack of yellowed old photos and handwritten investigation reports were neatly arranged, and a yellowed ancient book was inserted upside down on the side, with three large, bold characters on the cover.

Qi Refining Technique.

boom!

A thunderous roar exploded in Qin Quan's mind, and countless chaotic thoughts surged into his head.

It really was it!

It was this very skill that brought utter destruction to the Qin family, causing them to be wiped out overnight.

But he just couldn't understand how the secret manual passed down by the Qin family for generations could have fallen into Song Qingshu's hands.

Suppressing his turbulent emotions, Qin Quan immediately picked up the photos and handwritten investigation records in the box and carefully examined them.

The information is extremely detailed, including on-site photos of the raging fire, the devastated ruins after the fire was extinguished, and detailed evidence collected after the fire site was cleared.

Even the old newspapers from that year were carefully cut and preserved by Song Qingshu, each piece serving as irrefutable evidence of the tragedy.

As the photos flashed before his eyes, images of his loved ones' tragic deaths flooded his mind, causing Qin Quan unbearable pain, as if his heart was being repeatedly pierced by a sharp blade.

He suppressed the heavy sorrow in his heart and continued to look through the box, his gaze settling on an old kraft paper envelope at the bottom.

"To my son, Qin Potian!"

The handwriting on the envelope was strong and familiar, etched into his very bones; it was his father's handwriting.

In an instant, Qin Quan's brain went blank, his pupils dilated, and he stared intently at the letter home, his breath catching in his throat.

"President Song, what exactly happened?"

He looked up and asked, his voice trembling uncontrollably.

Song Hongyan was also completely taken aback and shook her head repeatedly.

"I didn't know. We never opened it and had no idea there was a letter inside."

Tan Min, who was standing nearby, quickly spoke up to explain.

"Mr. Qin, this is something the old lady specifically asked us to pass on."

Qin Quan's expression hardened.

"Grandma Song?"

"Exactly."

Having received confirmation, Qin Quan asked no further questions, ran his fingertips over the envelope, and carefully checked the seal.

After confirming that there were no signs of tampering and that the letter was intact, he carefully opened it and began to read it.

Familiar handwriting came into view, each word heavy, each sentence piercing the heart.

The letter contained all of his father's dying words and...the truth.

Qin Potian had long foreseen that they would suffer such a great calamity, so he entrusted the Qin family's secret manual, the Qi Refining Technique, to Old Madam Song for safekeeping in order to preserve the last thread of the Qin family lineage.

At the same time, it reveals a shocking secret.

The Qin family of Jincheng originated from the Qin family of Kyoto and is a branch of the Qin family of Kyoto.

In this large family, apart from Qin Quan's second uncle and aunt, none of the other family members can be trusted.

Finally, he sternly warned Qin Quan that he was absolutely not allowed to investigate old cases or seek revenge without authorization before he had cultivated the Qi Refining Technique to the minor completion stage.

The entire letter is divided into two main parts.

First, to clarify the origins of the Qin family branch and the main family in Kyoto; second, to desperately dissuade Qin Quan from seeking revenge rashly and to bide his time.

After reading all the content, Qin Quan appeared calm on the surface, but in his heart, a raging storm was brewing, and his killing intent was surging wildly.

The letter did not explicitly name the enemy, but it implied that the Qin family massacre originated from the powerful Qin family in the capital.

"What a fine host!"

Qin Quan's five fingers suddenly clenched, his knuckles turned white, and a loud cracking sound came from his bones.

"Even if you are of my bloodline, so what?"

"You slaughtered my entire family! This is an irreconcilable hatred! One day I will personally go to the capital and make you all pay for your blood debt."

Boom!

A powerful shockwave swept through the entire private room with terrifying force. Caught off guard, the four women, including Song Hongyan, were instantly forced to stagger by the shockwave and fell back into their seats, their faces deathly pale.

"Mr. Qin, please calm down!"

"Mr. Qin, please don't get angry and harm your health!"

Hearing the urgent voices of two women behind him trying to dissuade him, Qin Quan suddenly snapped back to his senses and suppressed the raging aura emanating from him.

He suppressed his surging murderous intent, turned around, and apologized in a deep voice.

"I'm sorry, I lost my composure."

"I accept this generous gift."

Qin Quan's gaze was firm as he spoke solemnly.

"From this day forward, I will ensure the safety of the Song family."

Upon hearing this, the four women felt a huge weight lifted from their hearts.

They delivered this evidence overnight, partly out of gratitude to Qin Quan for saving their lives, and partly to secure this favor and ensure the Song family's safety.

Now that our goal has been achieved, how can we not be happy?

"Please make yourselves at home. I'll take my leave now."

Qin Quan knew that the four women were unaware of the past secrets and had no intention of lingering there, so he turned and left.

Song Hongyan and the other three quickly stood up and bowed in unison to see them off.

"Take care, Mr. Qin!"

……

Rental housing in the suburbs.

Qin Quan sat cross-legged on the bed, took out the yellowed Qi Refining Manual again, and studied it word by word, becoming more and more alarmed as he read.

The Qi Refining Technique has five levels, corresponding to the Qi Refining Realm, Foundation Establishment Realm, Golden Core Realm, Nascent Soul Realm, and Deity Transformation Realm.

"This is actually a legitimate cultivation technique, capable of leading all the way to the Nascent Soul Realm!"

He finally understood why this cultivation manual had become the root cause of the Qin family's annihilation.

Who wouldn't be tempted by what's inside?

It's even comparable to his Pure Yang Skill.

Qin Quan immediately focused his mind and tried to cultivate according to the mental techniques and incantations.

This method perfectly suited his own foundation, and he was able to learn it very quickly, grasping the path to cultivation in no time.

A night of arduous practice passed in the blink of an eye.

In just one night, he cultivated the Qi Refining Technique to the second level, the Foundation Establishment Realm.

"Have you finished your cultivation?"

Qin Quan had just opened his eyes when he saw Jiang Yao sitting quietly by the bed, her eyes gentle and her smile faint.

"I made breakfast, let's eat together."

"it is good."

After a night of arduous training, Qin Quan was already quite hungry. He picked up his bowl and chopsticks and began to eat heartily.

During the meal.

Jiang Yao spoke as she ate:

"Huang Lüdeng has been handed over to the Hidden Dragon Headquarters for handling. In addition, according to Miao Cuihua's confession, Jin Hai and Liu Chuanwu were the moles who secretly tipped off the Gu Poison Sect."

"It's just that the leader of the Martial Alliance, together with Fifth Master Qin, intends to exert pressure and protect the two of them to the death."

"Can they protect it?"

Qin Quan scoffed.

"It's hard to say."

Jiang Yao, however, looked solemn, lowered her voice, and her face clearly showed some worry.

"Master Qin will arrive in Jincheng today. He's coming not only for Jin Hai and Liu Chuanwu's affairs, but also for Qin Lang..."

Jiang Yao hesitated, as if she wanted to say something but then stopped.

Qin Quan saw through her worry at a glance and said calmly:

"Even if he doesn't come looking for me, I'll go looking for him. Since he's here, let's settle all our old and new scores together."
